HU-CAPLOCKING DEVICE.

Application led September 4, 1919. Serial No. 321,574.

To all whom t may `cof/wem:

'Be it known that I, --EDWARD G. BUDD, residing at Philadelphia, countyof Philadelphia, State of Pennsylvania, have invented certain new anduseful Improvements in Hub-Cap-Locking Devices, of which I declare thefollowing to be a full, clear,\and exact description.

This invention relates to improvements in hub cap locking devices fordemountable wheels.

One of the objects of my invention is to provide an improved lockingdevice for the hub caps of demountable wheels which is simple inconstruction, fool-proof in operation, locks the hub cap positively tothe inner hub and is ofsuch a nature as not to detract from'the artisticappearance of the hub cap.

Another object of my invention is to provide a hub ca of simpleconstruction having a locking evice which can be manufactured in largequantities at a' comparatively low cost.

Another object of my invention is to provide a hub cap locking device ofsuch a nature that the hub cap may be screwed up by hand, but will belocked against rotation to unscrew the hub cap, except when the hub capwrench is properly applied.

Further objects, and objects relating to economies of production andoperation and details of construction, will definitely appear from thedetailed description to follow. I accomplish the objects of myinvention, in

. one instance, by the devices and means described in the followingspecification. My invention is clearly delined and pointed out in theappended claims. A. structure, constituting a preferred embodiment of myinvention, is illustrated in the accompanying drawing, forming a part ofthis specicationz in which:

Figure I is a transverse, sectional view through the hub of ademountable wheel embodying my invention.

Figure II is a transverse, sectional View through the hub cap taken onthe line 2 2 of Figure I.

Figure III is a transverse, sectional view through the hub cap taken onthe line 3 3 of Figure I.

Figure IV is a view of the outer end of the hub and hub capcorresponding to Fig- Flgure V is a view corresponding to Figure'II butshowing the wrench applied to release the latch.

In the drawings, similar reference numerals refer to similar partsthroughout the several views and the sectional views are taken lookingin the direction of the little arrows applied to the section lines.

Considering the numbered parts of the drawing, I have shown ademountable wheel comprising the inner hub 15 and the outer hub 18. Theaxle shaft 11 extends within the usual axle casing 10, upon the outsideof the end of which the bearings 12 are mounted. A bearing retainer 13encloses said bearin s and has a radially extending flange to Whlch thebrake drum 14 is bolted by bolts which also` extend through a radialflange on the inner end of the inner hub so that the brake drum, thebea-ring retainer, and the inner hub are bolted together, with thebearing, and the bearing retainer housed within the inner end of theinner hub, as shown in Figure I of the drawing. The outer end of theinner hub is cylindrical or cup-shaped in form and internally threaded,and a plurality of bevelled ratchet teeth 17 are formed on the innersurfacel of the cup-f An outer hub 18 is removably mounted on v theinner hub 15 and provided with pressed out seats 19 and 2O for the endsof the spokes. Any suitable intermeshing means are provided to preventrelative rotation of the outer and inner hubs.- The outer end of theouter hub 18 is bevelled at 21. In Figure I of the drawing, I have showna rear wheel, the inner hub being so formed so as to be mounted on therear axle. It is to be understood, of course, that my invention is bodyportion, and the inner face of said head has a bevelled surface engagingand co-operating with the bevelled end 21 of the outer hub. An openingis provided through the side wall of the body portion 23 of the hub capbetween the inner face of the head and the threaded portion of saidbody, and there is also provided an opening 24 through the side wall ofthe head in line with the previously described opening through the sidewall of the body. A latch 25 is mounted within the hub ca and has abevelled tongue 27 which is slidaby mounted in the opening through theside wall of the body portion of the hub cap and engages the internalbevelled ratchet teeth 17 of the inner hub as clearly `shown in FigureIII. The latch 25 also has an actuating pin 26 which is slidably mountedin the opening 24. rIhe tongue 27 and the actuating pin 26 extendlaterally from the latch 25 at substantially fright angles thereto. Aguide pin 28 extends from the latch 25, in the opposite direction fromthe tongue 27; and is in line lwith a similar ide pin 30 which extends`laterally from t e side wall of the hub cap at a int diametricallyopposite. A compresslon spring 29 is compressed between the latch 25 andthe side wall of the hub cap, the ends of said spring being centeredaround the pins 28 and 30.

To. rotate the hub cap, I use a wrench 31 Y having a shoulder 32 and acurved arm 34,

from the end of which a pin 33 projects latorally; When it is desired torotate the hub cap, the pin 33 is inserted in the openin 24,

and the shoulder 32 engages the side o the head of the hub cap, thusgiving the wrench a grip on the hub cap by means of which it may berotated. The insertion of the pin 33 in the openin 24 presses back theactuating pin 26 an the latch 25 against the pressure of spring 29, thuswithdrawing the bevelled tongue 27 from engagement with the bevelledratchet teeth 17 so that the hub cap may be rotated freely. As soon asthe wrench is removed, the spring 29 presses back the latch so that thetongue 27 moves into enga ement with the ratchet teeth, the bevel of t etongue 27, .and of the ratchet teeth 17, being such as to permit therotation of the hub cap in a direction to screw up the hub cap, whilepreventing all rotation in the opposite direction. rIhe end of theactuating pin 26 is normally substanthe operation of this locking deviceand1 further description is unnecessary. Itis apparent that it may bemade of few parts, and

opening.

meente readily yields itself to embodiment in a hub in the use (if thistype of locking device, the outer end or head of the hub cap may becylindrical and of very substantial appearance, so that thisconstruction does not detract from the artistic appearance of the hubcap.

I am aware that the articular embodiment of my invention, which I haveshown and described here, is susceptible of considerable variationwithout departing from the spirit thereof, and, therefore, I desire toclaim the same broadly, as well as specificall as indicated b theappended claims.

I-aving thus descri ed my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A device ofthe class described comprising the combination of an innerhub, an outer hub removably mounted thereon, a hub cap detachablymounted on one of said hubs and havin y an uninterrupted surfaceengaging the ot er to hold said hubs in engagement, said hub cap havinga pair of transverse alined openings through the side wall thereof, anda latch having a tongue slidably mounted in one of said openings and anactuating pin slidably mounted in the other 2. A. device of the classdescribed comprising the combination of an inner hub, an outer `hubremovably mounted thereon, a hub cap detachably mounted on one of saidhubs and havin an uninterru ted surface engaging the ot er to hold saihubs in engagement, `said hub cap having a pair of aligned openings inlthe side wall thereof on opposite sides of said surface, and a latchhaving a tongue slidably mounted in one of said openings and anactuating pin slidably mounted in the other opening.

3. A device of the class described comprising the combination of aninner hub, an outer hub removably mounted thereon, said inner hub havinga plurality of internal ratchet teeth formed therein, a hub cap screwedon the inner hub and having an uninterrupted -surface engaging the outerhub to hold said hubs in engagement, said hub cap having a pair ofopenings through the side wall thereof, a latch extending in a directionparallel to fthe axis of said hub cap and reciprocable radiall thereofand.. having a bevelled tongue sli ably mounted in one of said openingsand engagin said ratchet teeth and an actuating pin slidably mounted inthe other opening, and a spring compressed between said latch and theside wall of said hub cap.
